1.Either measure
the inside of the enclosure or subtract 1.5” (for.75” for ¾”
wood) from each of your external measurements.

2. Use the
appropriate formula to find volume in cubic inches.

a. LXWXH
for a rectangle or square - Example-1

b. (L1
+ L2) x H x W for a wedge - Example-2

2

c. Pie r2
x L for a cylinder - Example-3

d. For an odd shape you can use a
known volume container to fill the shape with either
water or packing material. While filling the shape,
count the number of times you refill the
container. Multiply volume of the container by the
number of times you had to fill it to calculate the
enclosures volume -
